Patent CA-2358252-A1 (CA)
Title: Distributed processing systems incorporating a plurality of cells which process information in response to single events
Inventor: ROBINSON JEFFREY I
IPC: H04M3/42
Filed: 2000-01-05
Abstract: A distributed processing system includes a plurality of cells where each cell processes information in response to a type of event, and cells communicate with each other according to an (asynchronous) event-reaction protocol.  According to one embodiment, each cell is responsive to a single type of event and includes a plurality of scripts which are executed upon the occurrence of an event of the appropriate type. At least some scripts include directions to send information to one or more scripts in another cell. According to another embodiment, some cells communicate with other cells according to a (synchronous) streaming protocol and other cells communicate according to an (asynchronous) event-reaction protocol. The cells communicate with each other via a shared memory or via a communications bus. The communications protocol utilized by the cells enables the use of virtually any networking medium.  Thus, cells may reside in the same chip or may be separated from each other by thousands of miles.

Patent CA-2362062-A1 (CA)
Title: Self oscillating power converter circuit
Inventor: FRENCH JOHN
IPC: H02M3/338
Filed: 2000-01-05
Abstract: A self oscillating power converter uses two MOSFET transistors connected across first and second primary windings. Each MOSFET is controlled using a gate control circuit located in a feedback path. Each gate control circuit is driven by a gate drive winding which is transformer coupled to a primary winding and which is phased with the primary winding such that regenerative feedback causes accelerated sequential turn-on and turn-off of the associated MOSFET transistor. Each feedback path includes a capacitor for charging in response to the voltage generated across the gate drive winding to initiate turn-on of the MOSFET transistor and a resistor for discharging the capacitor to initiate turn-off of the MOSFET transistor. The power converter can be configured as a push-pull converter in either a common-drain or common-source configuration. The power converter can also be configured such that at least one MOSFET transistor is capacitively coupled to a primary winding. Further, the power converter can be configured as either a full-bridge or a half-bridge converter.

Title: Rotational-part supporter
Inventor: YAMADA KIKUTA
IPC: F16N7/38
Filed: 2001-12-27
Abstract: The invention provides a rotational-part supporter in which one of either an inner part or an outer part is fixed, and the other one is rotated, and a main rotational shaft lies between the inner and outer parts. A revolving speed below a revolving speed based on a lubrication lifetime predicted for each rotational bearing (3) is stored in a memory (61) disposed in a lubricant supply controller (6). When a revolving speed obtained by actual rotation reaches the stored revolving speed in the rotational bearing (3) after supplying a lubricant, the controller (6) issues a signal indicating that a lubricant should be newly supplied, and thereby a safe operation can be realized.

Title: Method of controlling optical signal power at an add/drop node in a wdm optical communication system
Inventor: YOUNG SCOTT D
IPC: H04B10/572
Filed: 2002-05-09
Abstract: Optical signal power levels for selected optical channels processed within an add/drop node in a wavelength division multiplexed (WDM) system are adjusted as a function of variations in signal power in an incoming WDM signal caused by gain ripple. In particular, a "ripple fitting" method is described whereby the optical signal power of individual optical channels being added at the add/drop node are adjusted to levels that correspond to the ripple profile of other optical channels being routed through the add/drop node. In this manner, the gain ripple in the WDM signal being output from the add/drop node approximately corresponds to the gain ripple in the incoming WDM signal at the node.

Title: Photolytic and photocatalytic reaction enhancement device
Inventor: SPEER SAMUEL E
IPC: B01J35/00
Filed: 2001-03-21
Abstract: A photolytic and photocatalytic reaction enhancement device comprising a catalyst coated, fluid permeable fixed-substrate material preferably constructed of either pure titanium or tungsten or their alloys that is oxidized or anodized to form a titanium dioxide or tungsten oxide layer, respectively, or a corrosion-resistant metal alloy that can be coated with a photocatalyst. In a preferred embodiment, the substrate may be a glass, polymeric or ceramic composition containing micropores, channels or conduits which receive oxidizing, reducing and/or pH agents. The catalyst is a semiconductor such as TiO2, WO3, Fe2O3, or titanate-based materials compatible with the process and may be metallized. The structure and configuration of the substrate each serve to optimize both photocatalyst surface area and turbulence of the target fluid within the maximum UV illumination area of the reaction chamber, thereby enhancing photocatalytic reactivity. The substrate is generally comprised of a length of mesh or cloth-like material which, in the preferred embodiment is folded or "pleated" in accordion-like fashion.  A plurality of panels are created by the folding, each being adapted with a centrally located aperture for slidable reception of the UV light source there through. The edges of each aperture may be optionally modified with a special coating to prevent damage to the scratch-prone outer surface of the UV source as well as actually clean the surface through manual contraction and extension of the accordion-like substrate.  Alternatively, a UV transmissive sleeve may be employed between the UV source surface and the subject invention. The subject device may be removably installed within conventional and more novel, commercially available UV chambers without modification thereof or the use of invasive mounting means.

Abstract: A la réception d'un signal demandant une nouvelle transmission de données, un bloc (104) de commutation de signal de transmission produit un signal de sortie d'un bloc (102) de codage de correction des erreurs pour un bloc (106) de modulation, et à la réception d'un signal de demande de retransmission de données, le bloc (104) de commutation du signal de transmission produit un signal stocké dans un tampon (103) pour le bloc (106) de modulation. Un bloc (105) de décision du procédé de modulation commande le bloc (106) de modulation, à la réception d'un signal demandant une nouvelle transmission des données, de manière à effectuer la modulation à l'aide d'un procédé de modulation du débit maximal. D'autre part, à la réception d'un signal demandant une retransmission des données, le bloc (105) de décision du procédé de modulation commande le bloc (106) de modulation de manière à effectuer la modulation au moyen d'un procédé de modulation pour la retransmission. Le procédé de modulation utilisé pour la retransmission peut être un procédé dans lequel le débit maximum est multiplié par une constante prédéterminée (par exemple, 0,5) ou peut être un procédé fixé pour un type de modulation de phase tel que BPSK ou QPSK. Ceci réduit le nombre de retransmissions de données, ce qui a pour effet d'améliorer l'efficacité de la transmission.

Title: Wireless communication system
Inventor: FANTASKE STEVE
IPC: H04W92/02
Filed: 2002-11-13
Abstract: A wireless network communication system consists of an access server for facilitating communication between a network resource interfacing with the access server over a land-based network and a wireless communications device interfacing with the access server over a wireless network. A message intended for transmission from the wireless communication device to the network resource is transmitted to the access server over a wireless network as a number of message datagrams. Upon receipt of the message datagrams over the wireless network, the access server generates and transmits to the wireless communication device an acknowledgment datagram indicating successful receipt of each message datagram, and transmits the successfully received message datagrams to the network resource over the land-based network. If a message datagram is not acknowledged, the wireless communication device continues to retransmit the unsuccessfully transmitted message datagram at a retransmission rate based on a running average of acknowledgment times for successfully transmitted ones of the message datagrams.
